HANGER FOR CAR-DOORS.

Specification of Letters Patent.

Patented Apr. 12,1921.

Application filed December 15, 1920. Serial No. 431,030.

T0 all 'whom t may concern.'

Be it known that I, CHARLES H. JORDAN, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful lmprovements in Hangers for Car- Doors, of which the following is a speciication, reference being had to the accompanying drawings. V

The present invention has for its object to provide an improved hanger especially adapted for car doors, though it may be used in connection with other classes of doors, involvingmeans for preventing bulging of the door, and at the saine time preventing' the door from ainniing or binding during its opening and closing movement.

Another purpose involves the provision of means such as braces of metal connected to the door, and in turn to the journal pins of the rollers of the hanger mechanism, in order to keep the rollers true and in perfect alinement.

Still another purposeresides in the provision of channel guides for the rollers of the door, the guides being arranged adjacent the top and bottom of the door opening, there being relatively narrow slots in the guides for the reception of the journals of the rollers or wheels, wherebv the rollers or wheels may operate freely in the guides.

its a further purpose, itis the aim to provide means such as openings in the bottoms of the channel guides, for carrying off debris and rain water, as well as melted snow and sleet, and furthermore it is the aim to provide anti-frictional bearings for the rollers o r wheels, to enable them to easily operate in the guides.

lVhile the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible of changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed. j

The invention comprises further features and combination of parts, as will be hereinf.

after set forth, shown in the drawings and claimed.

In the drawings Figure l is a view in side elevation of a portion of a railroad car, showing the improved-hanger mechanismy asapplied thereto for supporting the car door.

Fig. 2 is a view in side elevation showing thev door open and the upper part thereof broken away, showing the hanger mechanism at ythe top partly in section, and showing the hanger mechanism at the bottom in elevation.

Fig. 3 is a vertical sectional view on line 3-3 of Fig.V l.

Fig. et is a longitudinal sectional view through the upper hanger mechanism of the door.

Referring more especially to the drawings, l designates a portion of a car provided with a door opening 2, and 3 and i denote channel guides, which may be constructed of any suitable metal, preferably sheet iron, bent as shown in cross section.

Arranged adjacent to the side of the car is a slidable door 5, which may be any conventional construction, and adapted for closing the door opening.

Extending transversely of the door adjacent the top and bottom thereof are journals or shafts 6, which have washers 7 and 8 thereon adjacent the inner and outer faces of the door, there being nuts 9 and l0 threaded on the journals for holding the washers in contact with the door, thereby providing se-y cure mountings for the journals. The outer portions of the journals are threaded as shown, and secured by bolts ll to the exterior face of the doorare metallic straps l2, between whichand the door washers 13 are interposed, there being nuts applied to the bolts to hold the plates or straps in position. -The lower ends of the lower straps l2 and the upper ends of the upper straps have apertures to receive the journals 6, there being` sleeves lll interposed between the nuts 9 and the plates or straps 12, to hold the journals rigid, and to prevent them from becoming displaced as the result of constant use. Toinsure holding the sleeves in positionv and the strapsor plates fixed, nuts 15 are threaded on the journals adjacent the outer face ofthe straps l2. j

` Rollers or wheels 17 are `mounted upon the inner ends of the journals 6, there being heads, 18 for holding the rollers on the inner ends of the journals. The nuts l() are provided with cone bearings, which copcrate with similar bearings of the heads 18 of the journals, for the purpose of holding rollers or wheels to freely rotate in the channel guides.

It will be noted that there are four wheels,

carried by the journals of the lower part of the door, while there are three wheels carried by the journals of the upper part of the door, thereby acting to prevent the door from bulging outwardly, as is usually the case in connection with hangers now in use, which give considerable trouble when opening and closing car doors.

The lower floor of the channel guides are provided with apertures or openings 19, for carrying off the debris, rain water and melted snow or sleet, thereby preventing freezing of the same in the guide, which would undoubtedly prevent free movements of the door as well as the rollers or wheels in the guides. These openings or apertures are lo@ catedtoward the ends of the guides, so that the water and the like may travel to either end of the guides. Abutmentstrips 20 are arranged adjacent the opposite ends of the guides, tol limit the door in `its opening or closing movement.

Adjacent one of the vertical edges or j ambs of the door opening 2 a vertical strip 2a is fixed, to close the space between the door and the side of the car, at a point adjacent the door opening. yThis strip 2a is kfastened between the upper and lower channel guides as shown. rllhe slots of the channel guides are relatively narrow, in fact only wide enough to permit freedom of movement of the nuts l0 and the bevel col lars l0a longitudinally. rThe collars 10a are threaded on the journals, so as to permit of the assembling of the rollers or wheels on the journals, there being ball bearings `17a between the bevels of the collars l0a and the heads 18, so as to permit free movements of the rollers or wheels.` l

IT he invention having been set forth, what is claimed as being useful is l. In a carV door hanger, the co.l bination with upper and lower channel guides, of a door arranged adjacent the door opening of the car, journals adjacent the upper and lower parts of the door and extending transversely at right angles thereto, said journals having inwardly and outwardly extending parts, rollers or wheels mounted on the inwardly extending parts, means for holding the wheels or rollers thereon, straps connected to the outer face of the door and having their ends engaged with the end portions of the outwardly extending parts of the journals, sleeves mounted on the outwardly extending parts under the extremis ties of the straps, and means such as nuts engaging the extremities of the outwardly extending parts to hold the straps and sleeves in position, thereby reinforcing the journals rigidly at right angles to the door.

2. In a car door hanger, the combination with upper and lower channel guides, of a door arranged adjacent the door opening of the car, journals adjacent the upper and lower parts of the door and extending transversely at right angles thereto, said journals having inwardly and outwardly extending parts, rollers or wheels mounted on theV inwardly extending parts, means for holding the wheels or rollers thereon, straps connected to the outer face of the door and having their ends engaged with the end portions of the outwardly extending parts of the journals, sleeves mounted on the outwardly extending parts and the extremities of the Straps, and means such as nuts engaging the extremities of the outwardly extending parts to hold the straps and sleeves in position, thereby reinforcing the journals rigidly at right angles to the door, and means on the journals immediately adjacent the outer face of the door to prevent axial movement of the journals relatively to the door, before the reinforcing and outer bracing means are applied.

ln a car door hanger, the combination with upper and lower channel guides, of a door arranged adjacent the door opening of the car, journals adjacent the upper and lower parts of the door and extending transversely at right angles thereto and provided with inwardly and outwardly extending parts, rollers mounted on the inwardly extending parts and engaging the channel guides, said outwardly extending parts terminating a substantial distance from the outer face of the door, straps connected to the outer face of the door and extending at substantial angles to the door upwardly and downwardly and engaged with the end portions of the outwardly extending parts of the ournals, means on the outwardly extending parts of the journals spacing the straps substantial distances-from the door, and means for holding the straps in engagement with the journals and said spacing means.

ln testimony whereof I hereunto aflix my signature. i
